The Easter egg can be found in the 1977 game Starship 1 and was uncovered by ex-Microsoft exec Ed Fries, who played a big role in creating the original Xbox. Fries details his journey in discovering the earliest video game Easter egg in an amusing blog post. Using a special sequence of input commands, the Easter egg makes the phrase “Hi Ron!” appear on-screen. The message is a reference to Atari game programmer Ron Milner, who coded Starship 1.
